You start an application that tells you that a new version is available. You suddenly realize that with every start this application connects to the developer's server. Even statistics information about your computer may be sent this way. Little Snitch helps you avoid this situation.

Trojan horses - i.e. programs transmitting unconsciously data stored on your computer - can be detected by Little Snitch and prevented on the transmission of data.
